This example will show you how to handle parent and child thread and switch between activities.
Algorithm:
1.) Create a new project by File-> New -> Android Project name it HandlerThreadActivity.
2.) Write following into main.xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/start_thread"></Button> </LinearLayout>
3.) Run for output.
Steps:
1.) Create a project named HandlerThreadActivity and set the information as stated in the image.
Build Target: Android 4.2
Application Name: HandlerThreadActivity
Package Name: com. HandlerThreadActivity
Activity Name: HandlerThreadActivity
Min SDK Version: 4.2
2.) Open HandlerThreadActivity.java file and write following code there:
package com.handlerthreadactivity; import android.app.Activity; import android.app.ProgressDialog; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class HandlerThreadActivity extends Activity{ private Button start; private ProgressDialog progressDialog; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); start = (Button) findViewById(R.id.Button01); start.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { // TODO Auto-generated method stub fetchData(); } }); } protected void fetchData() { // TODO Auto-generated method stub progressDialog = ProgressDialog.show(this, "", "Loading..."); new Thread() { public void run() { try { Thread.sleep(800); } catch (InterruptedException e) { } messageHandler.sendEmptyMessage(0); } }.start(); } private Handler messageHandler = new Handler() { public void handleMessage(Message msg) { super.handleMessage(msg); progressDialog.dismiss(); } }; }
